wrong bro
BK
Cacl2 act as a acclerator in concrete which reduces setting time (i mean helps to get fast strength to concrete ) due to which we can reduce curing time , it increses hydration rate ..... am i correct ??? If i am correct please why option 2 not consider as answer ....cacl2 is admixture which increses strength indirectly by affecting other factor .....

  2. A layer of dry bricks put below the foundation concrete, in the case of soft soils, is called 1) soling 2) shoring 3) D.P.C. 4) None of these


  3. Distemper is used on 1) plastered surface not exposed to weather 2) plastered surface exposed to weather 3) roof tops 4) un-plastered brick wall


  4. The purpose of the soundness test of cement is 1) to determine the presence of free lime 2) to determine the setting time 3) to determine the sound proof quality of cement 4)to determine the fi neness


  5. The separation of water on the fresh concrete is known as 1) segregation 2) hydration 3) bleeding 4>None of the these


  6. The sub-classification of sedimentary rocks 1) volcanic and plutonic 2) mechanical, chemical, organic 3) intrusive, extrusive 4) stratified, un-stratified


  7. The Paints that are most resistant to fire are 1) enamel paints 2) aluminium paints 3) asbestos paints 4) cement paints


  8. Terra cotta, in buildings, is used for 1) insulation 2) ornamental work 3) sewage lines 4) sanitary services


  9. The indentation provided in the face of the brick is called_ 1) frog 2) pallet 3) strike 4) None of the these


  10. Most of the stones possess the specific gravity in the range of 1) 1 to 1.5 2) 1.5 to 2.0 3) 2.4 to 2.8 4) 3 to 4


  11. The workability of concrete can be improved by 1) More sand 2) More cement 3) More fine aggregate 4) Fineness of coarse aggregate


  12. Density of concrete 1) Increases with a decrease in the size of aggregate 2) In independent of the size of aggregate 3) Increases with increase in the size of aggregate 4) All options are correct


  13. Concrete gains strength due to 1) Chemical action of cement with coarse aggregate 2) Hydration of cement 3) Evaporation of water 4) All optons are correct


  14. Addition of calcium chloride in concrete results in 1) Increased strengtn 2) Reduction in curing period 3) Retardation of loss of moisture 4) All optons are correct


  15. Rate & Review 5 SHARE RATE & REVIEW COMMENT & FEEDBACK


  16. Modulus of elasticity for concrete improves by 1) Shorter curing period 2) Age 3) Higher W.C. ratio 4) All optons are correct
